A Smartphone-based Ultrasonic Machine That Can Detect Cancer

Scientists have developed a machine the size of an electric razor that is capable of detecting cancer

A machine called Butterfly IQ, developed by scientists from Butterfly Network, a US-based start-up, can help detect cancer easily at home. The novel smartphone-based portable ultrasound machine works by shooting sound waves into the body and capturing the echoes.

An MIT Technology Review stated that, although sound waves are generated by a vibrating crystal, this machine uses 9,000 tiny drums etched into a semiconductor chip to create sound waves.
